# \Numeric With Format
#
# Provides options for converting numbers into formatted strings.
# Options are provided for phone numbers, currency, percentage,
# precision, positional notation, file size, and pretty printing.
#
# This method is aliased to <tt>to_formatted_s</tt>.
#
# ==== Options
#
# For details on which formats use which options, see ActiveSupport::NumberHelper
#
# ==== Examples
#
# Phone Numbers:
